- If the output switch is driven into hard saturation (non-arlington configuration) at low switch currents ( 300 mA) and high driver currents ( 30 mA), it may take up to 2.0 ms for it to come out of saturation.
- This condition will shorten the off time at frequencies 30 kHz, and is magnified at high temperatures.
- If a non-Darlington configuration is used, the following output drive condition is recommended: Forced b of output switch : * The 100 W resistor in the emitter of the driver device requires about 7.0 mA before the output switch conducts.

- ORDERING INFORMATION
Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
